Bicrystals with 89° <10▪0> symmetrical tilt boundary inclined at different angles to the free surfaces were annealed in the field of 17T. Boundaries migrate reorienting almost perpendicular to the surfaces. The observed effect was due to combination of magnetically induced and capillarity driven boundary migration. The absolute boundary mobility was measured to be about 2.5 x 10-8m4/Js.
